What Causes This Fear?
| Build Your Skills!
The fear of public speaking is a type of social phobia characterized by an intense fear of social or performance situations. Social phobias can trigger physical symptoms, like heart palpitations, tremors, sweating,
diarrhea, confusion, and blushing.
What Causes This Fear?
Researchers have not pinpointed the exact cause of public-speaking fear or other types of social phobias. But, some possible explanations include:
- Problems with the amygdala—Some researchers suggest the trigger may be a small structure in the brain called the amygdala. This is the central site in the brain that controls fear responses.
- Genetic link—Social phobias may also be inherited. For example, scientists have discovered a gene in mice that affects learned fearfulness.
- Problems with brain chemicals—Scientists are also exploring a biochemical basis for the disorder, with the idea that heightened sensitivity to disapproval may be hormonally or physiologically based.
Social phobias may also be fueled by environmental factors. For instance, a fear of public speaking may be acquired from observing the fear in others, a process called observational learning or social modeling.
The fear of public speaking can be being successfully treated by cognitive-behavioral therapy (CBT). During CBT, people learn to change negative thought patterns and behaviors. People can then confront audiences under the supervision of a trained therapist. Instead of fleeing from the fear, individuals confront their anxiety with a goal of steadily reducing the dread they once felt.
Selective serotonin reuptake inhibitors (SSRIs) and other types of medicines may also be used to treat the fear of public speaking.
